[intermediate/advanced] Speech Processing: Automatic Speech Recognition and beyond
Spoken language interfaces such as smart speakers and voice dictation systems have become commonplace. This course will give a tour of the several decades of progress that have made this possible, starting from the core task of automatic speech recognition but also including additional tasks involved in enabling computers to use speech in all of the ways that humans do. The course will describe in detail some of the most successful approaches, including both established methods and more recent advances such as deep representation learning.
